Continuous powder surface modification system

Abstract

The invention relates to a continuous powder surface modification system. The continuous powder surface modification system comprises a double-spiral feeder, a raw material bucket, a continuous powder modifier, a whirlwind powder collector, an electric cabinet, a pulse dust remover, a muffler, a centrifugal fan and a finished product spiral conveyor; the double-spiral feeder is arranged at a material outlet of the raw material bucket; the output end of the double-spiral feeder is arranged above a material inlet of the continuous powder modifier; the material outlet of the continuous powder modifier is connected to the whirlwind powder collector through a pipeline; a finished product outlet of the whirlwind powder collector is formed in the finished product spiral conveyor; the negative pressure of the whirlwind powder collector is connected with the pulse dust collector and the centrifugal fan; a raise dust collecting output of the pulse dust collector is formed in the finished product spiral conveyor; the muffler is also provided. The continuous powder surface modification system is high in adaptability for the type, granularity, shape and density of raw powder, high in dispersing capacity for powder and modifying agents, and convenient to adjust the modification temperature and dwell time, and can perform compound modification for the modifying agent and the powder through one machine; the continuous powder surface modification system has the advantages of being continuous to produce, stable in product quality, low in energy consumption, and free of pollution.

Description

technical field [0001] The invention relates to the field of environmental protection powder surface modification, in particular to a continuous powder surface modification system. Background technique [0002] Surface modification can improve the technical content and added value of non-metallic mineral powders, and is of great significance to improving the performance of modern materials and promoting the development of non-metallic mineral materials industry. At the same time, surface modification can significantly increase the filling amount of non-metallic mineral fillers and significantly reduce the amount of resin in polymer-based composites, which is of great significance for saving resin and even oil. [0003] Since the 1980s in my country, the dry modification process has been dominated by high-stirrer intermittent mode. This process is not very adaptable to the type, particle size, shape, density, etc. The performance is not strong, and the modification temperatur...
